Niobophosphate Glass as Sintering Additive for Al₂O₃-YAG

Article Preview

Abstract:

In this study, the following compositions were produced: Al₂O₃-YAG laser with 2, 4, 6 and 15% by weight of niobophosphate glass (30mol%P₂O₅-30mol%Nb₂O₅-20mol%CaO-20mol%CaF₂). Sintered discs were characterized by scanning electron microscopy (SEM), X-Ray diffraction (XRD) with the refinement by the Rietveld method and density. The YAG-Al₂O₃ composite sintered at 1450 °C showed densification of 90%, which indicates the effectiveness of the sintering additive.
